Product Description:

The MDD090B-N-020-N2L-130GA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and placed in the MDD Synchronous Motors series. It is designed to work with compatible digital drive controllers, converting regulated drive current into rotary motion for axes that require accurate position and velocity control in automated machinery. Typical applications include packaging lines, material-handling gantries, and machine tools where repeatable motion is important. Its synchronous design supports closed-loop operation, so the connected controller can respond quickly to changing load conditions during acceleration, holding, and speed regulation.

At standstill, the motor can develop 7.2 Nm of continuous torque, giving the drive enough margin to support static loads without excessive heating. During operation, it is intended to run at a nominal speed of 2000 rpm, which provides a practical balance between dynamic response and service life. Rotor mounting is guided by a 130 mm centering diameter, allowing accurate alignment to gearboxes or direct mounting flanges. Command and diagnostic signals are returned through Digital Servo Feedback (DSF), which supplies position data to the controller for closed-loop motion control. Power and feedback leads terminate through a sealed connector interface, which helps keep wiring organized and reduces the chance of connection errors. The rotor is balanced to a standard grade so vibration remains suitable for normal operation in this frame size.

The wiring exits on side A, which gives the motor a fixed cable direction for machine layout planning. The unit is supplied without a blocking brake, so any holding force during a stopped condition must come from drive torque or an external holding device. It uses a plain shaft, and a shaft seal is fitted to help protect the internal bearings from splash and dust. The shaft is a single-ended design with no extension on side B. The motor uses size 090 with length code B and the standard housing style used for this frame.
